1
45 e+ bunches, 4-ns spacing, 0.9 mA/bunch
3.5 inch cylindrical v.c. 0.025 p.e./e+100% reflectivity dmax = Epeak = 310 eV Ib = 1.44e10 e+/bunch (0.9 mA) Resonance more clear with cylindrical vacuum chamber. Slight offset from n=10.
2
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Peaks at top and bottom of chamber more spread out on resonance. Corresponds to bigger effect for collector 1 than collector 9.
3
Again showing more spread in azimuth on resonance.
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Again showing more spread in azimuth on resonance.
4
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Higher energies on resonance, but need to correlate to position on wall.
5
Spatial distribution of cloud electron average energies.
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Spatial distribution of cloud electron average energies.
6
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Angles of incidence on wall more glancing on resonance. Consequences for RFA acceptance. More secondary yield in any case.
7
Higher yields on resonance. Higher energies and more grazing angles.
Compare n=0.5 with n=1.0 n=0.5 n=1.0 Higher yields on resonance. Higher energies and more grazing angles. ECLOUD SEY model sets cosQ < 0.2 to cosQ = 0.2 for yield calculation.
